IMPROVEMENT IN LOOM-PICKERS.

Specification forming part of Letters Iatent No. 155, [99, dated September 22, 1874; application tiled July 14, 1814.

To all whom it may concern: y

Be it known that I, SAMUEL MORTIMER, of Boston, Sulolk county, Massachusetts, have invented an Improvement in Pickers or Shuttie-Drivers, of which the following is a specilcation The drawings accompanying this specification represent, in Figure l a transverse, and in Fig. 2a longitudinal, section ofthe upper portion orhead oi' a picker-statt' embodying my iniprovemen ts.

In these drawings, A represents the upper portion or metallic head of a picker-stati, the horizontal spindle or guide upon which it plays being shown at B. The head A, over the spindle or guide B, has a slot, C, filled with cotton-waste or other absorbent of lubricants, for lubricating the spindle and bearing.

This arrangement prevents waste ot' lubricant. and lessens liability ot damaging the cloth by the spattering of the oil.

The lower portion, 1 of the head A is tubular, and serves to receive the picker or shuttle-driver, Whetherot' rawhide, leather, or other material, the outer end of the chamber D being closed by a screw, E. The portion of the part D that receives the picker-disks is of the same diameterthroughout, and extends as far as the front ofthe head.

The picker I prefer to employ in the form of disks or wafers a a, &c., of a diameter to till such chamber; and when one becomes worn or injured I remove it from the front of the head without disturbing the position ot the remaining ones. and place it in rear of the others, and between them and the screw E. This screw serves to advance the body of wafers, or to regulate their position within the chamber; and, in lieu of being a male screw, to enter the chamber, it may be a tubular cap to inclose the end of the chamber, in order that the latter may be of uniform diameter throughout. I am thus enabled to replace a worn picker with ease and celerity, while, by inclosing it within a metallic box or case, its durability is greatly enhanced.

The picker-head, formed with chamber D, extending through it from end to end, ot' equal diameter throughout, and provided with screw-plug E, which closes the rear of said chamber, and is adapted to operate on the picker-disks therein, as shown and set forth.

SAMUEL MOBTIMER.
